5. In the experiment, you will study an oscillator called a "torsion pendulum." In this case, the restoring "force" is the torsion constant of the wire that suspends the weight ) and the inertial term is the rotational inertia of the suspended mass. You will compare the periods of a suspended sphere and of a suspended cube. The rotational inertia of a sphere is I=(1/10)m D: where is the mass of the sphere and D is its diameter. The rotational inertia of a cube is where I =(1/6)m S: is the mass of the cube and S is the length of its side. If the cube and the sphere are suspended from the same wire, what is the expected ratio of their periods, T. /T, ?Assume that D=S. m.=0.20kg, and m=13ke
